Global Intra-Urban Land Use

This dataset provides land use maps for the year 2020 for all 4,000+ cities and metropolitan areas in the world with populations exceeding 100,000. The resulting product is the first freely available, global intra-urban land use maps at 5-meter resolution. The data includes a 4-tier land use taxonomy which at its root distinguishes open-space from built-up area. At the second tier, it subdivides the built-up category into nonresidential and residential areas. The third tier distinguishes formal from informal residential land use, and the fourth tier further subdivides formal and informal residential land uses into more detailed categories. Results of a separate road/street classification model based on the same methods are also provided. You can read more in the paper here
